Frontier Flight 601, traveling from Knoxville, Tenn. to Denver evacuated after a man on board was heard saying he had a bomb.

“We were probably only 30 minutes from Denver and the guy sitting across the hall from me told the flight attendant that he had a bomb in his backpack,” said passenger Nick Danneberger.

The flight crew immediately took action, and took the man’s backpack away from him, according to Danneberger

“They took other bags and put them around the backpack to kind of insulate it, and the flight attendants just tried to make sure we kept it in one spot,” he said.

The flight crew then rearranged the airplane and moved passengers away from the man.

The aircraft landed safely around 7:30 p.m.and was immediately taken to a remote area at DIA for police and FBI to handle. The FBI immediately took the man into custody and continues to investigate the case.

There is still no word on whether the FBI charged the man, or if they found a bomb inside his backpack.

The 136 passengers on the flight and five crew members deplaned safely, and were taken to the airport fire station for questioning.

Passengers said they are thankful that the flight crew was able to keep everyone calm and land the plane safely at the same time.
